.SH PARAMETERS
.LP
The parameter descriptions for \fBgss_store_cred()\fR follow:
.sp
.ne 2
.na
\fB\fIinput_cred\fR\fR
.ad
.RS 21n
The credential to be stored.
.RE

.sp
.ne 2
.na
\fB\fIcred_usage\fR\fR
.ad
.RS 21n
This parameter specifies whether to store an initiator, an acceptor, or both
usage components of a credential.
.RE

.sp
.ne 2
.na
\fB\fIdesired_mech\fR\fR
.ad
.RS 21n
The mechanism-specific component of a credential to be stored. If
\fBGSS_C_NULL_OID\fR is specified, the \fBgss_store_cred()\fR function attempts
to store all the elements of the given \fIinput_cred_handle\fR.
.sp
The \fBgss_store_cred()\fR function is not atomic when storing multiple
elements of a credential. All delegated credentials, however, contain a single
element.
.RE

.sp
.ne 2
.na
\fB\fIoverwrite_cred\fR\fR
.ad
.RS 21n
A boolean that indicates whether to overwrite existing credentials in the
current store for the same principal as that of the \fIinput_cred_handle\fR. A
non-zero value indicates that credentials are overwritten. A zero value
indicates that credentials are not overwritten.
.RE

.sp
.ne 2
.na
\fB\fIdefault_cred\fR\fR
.ad
.RS 21n
A boolean that indicates whether to set the principal name of the
\fIinput_cred_handle\fR parameter as the default of the current credential
store. A non-zero value indicates that the principal name is set as the
default. A zero value indicates that the principal name is not set as the
default. The default principal of a credential store matches
\fBGSS_C_NO_NAME\fR as the \fIdesired_name\fR input parameter for
gss_store_cred(3GSS).
.RE

.sp
.ne 2
.na
\fB\fIelements_stored\fR\fR
.ad
.RS 21n
The set of mechanism \fBOID\fRs for which \fIinput_cred_handle\fR elements have
been stored.
.RE

.sp
.ne 2
.na
\fB\fIcred_usage_stored\fR\fR
.ad
.RS 21n
The stored \fIinput_cred_handle\fR usage elements: initiator, acceptor, or
both.
.RE

.sp
.ne 2
.na
\fB\fIminor_status\fR\fR
.ad
.RS 21n
Minor status code that is specific to one of the following: the mechanism
identified by the \fIdesired_mech_element\fR parameter, or the element of a
single mechanism in the \fIinput_cred_handle\fR. In all other cases,
\fIminor_status\fR has an undefined value on return.
.RE

.SH DESCRIPTION
.LP
The \fBgss_store_cred()\fR function stores a credential in the current
GSS-API credential store for the calling process. Input credentials can be
re-acquired through \fBgss_add_cred\fR(3GSS) and \fBgss_acquire_cred\fR(3GSS).
.sp
.LP
The \fBgss_store_cred()\fR function is specifically intended to make delegated
credentials available to a user's login session.
.sp
.LP
The \fBgss_accept_sec_context()\fR function can return a delegated GSS-API
credential to its caller. The function does not store delegated credentials to
be acquired through \fBgss_add_cred\fR(3GSS). Delegated credentials can be used
only by a receiving process unless they are made available for acquisition by
calling the \fBgss_store_cred()\fR function.
.sp
.LP
The Solaris Operating System supports a single GSS-API credential store per
user. The current GSS-API credential store of a process is determined by its
effective UID.
.sp
.LP
In general, acceptor applications should switch the current credential store by
changing the effective UID before storing a delegated credential.
.SH RETURN VALUES
.LP
The \fBgss_store_cred()\fR can return the following status codes:
.sp
.ne 2
.na
\fB\fBGSS_S_COMPLETE\fR\fR
.ad
.sp .6
.RS 4n
Successful completion.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_CREDENTIALS_EXPIRED\fR\fR
.ad
.sp .6
.RS 4n
The credentials could not be stored because they have expired.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_CALL_INACCESSIBLE_READ\fR\fR
.ad
.sp .6
.RS 4n
No input credentials were given.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_UNAVAILABLE\fR\fR
.ad
.sp .6
.RS 4n
The credential store is unavailable.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_DUPLICATE_ELEMENT\fR\fR
.ad
.sp .6
.RS 4n
The credentials could not be stored because the \fIoverwrite_cred\fR input
parameter was set to false (\fB0\fR) and the \fIinput_cred\fR parameter
conflicts with a credential in the current credential store.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_FAILURE\fR\fR
.ad
.sp .6
.RS 4n
The underlying mechanism detected an error for which no specific \fBGSS\fR
status code is defined. The mechanism-specific status code reported by means of
the \fIminor_status\fR parameter details the error condition.
